The3rd Generation Partnership Project 2 (3GPP2) was a collaboration between telecommunications associations to make a globally applicable third generation (3G) mobile phone system specification within the scope of theITU'sIMT-2000 project. In practice, 3GPP2 was the standardization group forCDMA2000, the set of 3G standards based on the earliercdmaOne2GCDMA technology.
The participating associations wereARIB/TTC (Japan),China Communications Standards Association,Telecommunications Industry Association (North America) andTelecommunications Technology Association (South Korea).
The agreement was established in December 1998.
Ultra Mobile Broadband (UMB) was a 3GPP2 project to develop a fourth-generation successor to CDMA2000. In November 2008,Qualcomm, UMB's lead sponsor, announced it was ending development of the technology, favoringLTE instead.[1]
3GPP2 should not be confused with3GPP; 3GPP is the standard body behind theUniversal Mobile Telecommunications System (UMTS) that is the 3G upgrade toGSM networks, while 3GPP2 was the standard body behind the competing 3G standardCDMA2000 that is the 3G upgrade tocdmaOne networks that was used mostly in the United States (and to some extent also in Japan, China, Canada, South Korea and India).
GSM/UMTS were the most widespread 2G/3G wireless standards worldwide. Most countries used only the GSM family. A few countries, including China, the United States, Canada, Ukraine,Trinidad and Tobago, India, South Korea and Japan, used both standards.
3GPP2 had its last activity in 2013,[2] and the group has been dormant ever since. The 3GPP2 website was taken offline in 2023, primarily due to CDMA carriers deploying3GPP'sLTE instead of UMB the decade prior and later shutting down CDMA networks making the 3GPP2 redundant and unneeded. However, as of 2024 the 3GPP2 website has since come back online.
